A set including a first panel, a second panel and a mechanical locking device for locking the first panel to the second panel, the first panel includes a first edge surface and a first panel surface, the second panel includes a second panel surface, the first edge surface facing the second panel surface in a locked position of the first and the second panel, the mechanical locking device includes a panel groove at a surface of the second panel, a flexible tongue positioned in the panel groove, a rod-shaped element at the first edge surface and an insertion groove at the second panel surface extending from the second panel surface to the panel groove, the rod-shaped element having a first part at a first end, a second part at a second end and a recess in the second part, and a third part located between the first and second part.

Generally, an enclosure and method for assembling an enclosure including a plurality of frame members connected or interconnectable to generate a framework and a plurality of panels fastened or fastenable to the framework. In particular embodiments, enclosure and a method of assembling an enclosure from a kit including prefabricated enclosure sides including interconnectable frameworks fastened to panels configured to overlap adjacent panel edges at the corners upon interconnecting the frameworks.

A combination shelf includes at least four column units, at least two storage layers, and multiple clips. The column unit consists of two parallel, vertical poles on the left and right, and multiple connections connecting the left and right vertical poles. The clip has a vertical groove with a wing located on both sides at the lower halves of the front and rear ends of the groove opening. The grooves of the clips can be embedded by the vertical poles. The front and rear ends of both sides of the storage layer each offers an outward-opening U-shaped fastener. The front and rear edges of the lower half of the fastener each has a top pusher. The fasteners of the storage layer can each cover the exterior of the clips of the column units. The inner faces of the two top pushers each presses the two wings. By fitting together the corresponding bevels of the top pushers and the two wings, the clips and the fasteners press each other and therefore clamping the vertical pole.
